This, of course, means that Branch will be an unrestricted free agent this offseason.
Branch, 33, is a former second-round pick of the Cardinals back in 2007. He spent four years in Arizona before brief stints with the Seahawks and Bills.
The Patriots elected to sign him to a two-year, $4.3 million contract in March of 2015 and New England later brought him back on a two-year, $8.45-million contract last year. Branch was set to make a base salary of $1.7 million to go along with $1 million roster bonus for the 2018 season.
In 2017, Branch appeared in 12 games for the Patriots and recorded 12 tackles and no sacks.
